To @ZZ whom, it may concern.:

Be it known that I, MosEs G. HAwKINs, of Edinborough, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in Pendulum Engine-Governors for Vessels, which improvement is fully set forth in the following specication and accompanying drawings, in which- Figurel is aside view of my improved pendulum engine-governorfor vessels. Fig. 2 is a rear view of the same; and Fig. 3, a diagram of the oscillation of the boat, so as to represent the action of the governor.

The object of my invention is to construct and arrange a governor, which is placed in any suitable location, and preferably at the bow end of the boat, so that when the boat oscillates during rough weather the governor will regulate the supply-steam of the engine and prevent the erratic motion of the engine which is caused by the alternate submergence and withdrawal of the wheel from the water as the boat oscillates; and to accomplish this I provide a frame with a suitable set of guides, Within which frame is suspended a pendulum capable of vibrating or swinging in all directions, and this pendulum is connected with the valve in the supply-pipe of the engine, so that when the stern of the boat is raised and the blades of the wheel are partially or wholl y raised from the water the pendulum will cause the rocker-valve to close, and thus cut off the steam-supply, and when the stern of the boat sinks and submerges the blades to a greater depth than when the boat is raised upon an even keel the pendulum will throw the valve open, so as to admit a full head of steam, all of which will now b e fully set forth.

In the accompanying drawings, A is a frame or stand, of any suitable size or description, being preferably much larger at the base than at the upper end, so as to provide for a swinging'pendulum within. On each side of the frame is a curved guide-piece, B, to receive against their sides the ball-pendulum, which will be hereinafter described. The upper end of this frame is provided with a gimbal, C, having two of the cross-heads C hinged to the frame and the two opposite cross-heads, D, hinged or pivoted to the pendant or pendulum-rod E.

F is a ball or weight on the lower end of the pendulum-rod. Around this ball is placed, horizontally, a cushion, G, of any desired material, and the curved guide-bars B of the frame are so located that when the pendulum swings from side to side or in any direction the cushion G will strike against the guide-bars B or against the cross-rods H, which connect the ends of the guide-bars. It will thus be seen that the pendulum is free to swing within the frame on the gimbals C in any direction. Centrally on the gimbal is a standard, I, projecting upwardly, which has a slot, J, therein. Y K represents the steam-supply pipe for the engine. rPhis supply-pipe isprovided with an ordinary globe or rotating valve, or what is usually known as a butterfly-valve,77 or any of the balanced valves. The arm L, connecting with this valve, is slotted to correspond with the slot .I in the standard I. A connecting-rod, M, connects the valve-stem L and the standard or arm I, as shown, and either of the ends of this connecting-rod is capable of being moved up or down, so as to provide for the throw of the valve. Instead of having simply an ordinary bolt for the purpose of fastening the ends of the connectingrod, an adjusting-screw and hand-wheel may be placed on the valve-stem of the standard, so as to regulate the stem.

N represents the butterfly-valve having the disk vertically disposed to represent the position in Fig. l, wherein the boat is supposed to be upon a level keel.

In the diagram, Fig. 3, the line O represents the level and the dotted line P shows the inclined position assumed when the bow of the boat dips in the water in a rough sea. The stern of the boat, containing the wheel, would of course be elevated and withdrawn wholly or partly from the water. 'Ihe pendulum-rod E would, therefore, assume the position indicated at Q, Fig. 3, thus throwing the valve-stem over to the position indicated by dotted line R in Fig. 2 and cutting off partially or wholly the live steam tothe engine. Thus the steam will be cut off from the engine at a time when the propeller-blades are out of the water, and obviate the sudden dash or spurt of the engine occasioned by the withdrawing of the propeller-blade.
